Preferably, the touch control interface circuit 51 can include a driving interface and a testing interface, and can also include other interfaces. In the OLED touch control display device, by arranging the display area 4 and the touch control pattern areas 2 on the second surface 12 and the first surface 11 of the substrate 1, and connecting the touch control pattern areas 2 together through the via holes 3, the product thickness is reduced, and the flexibility performance and the folding performance of the OLED touch control display device can be effectively enhanced.
